Stock diameter is 29.5", the Defenders have a diameter of 30.8", so your bringing the tire 3/4" (approximately) closer to the steering knuckle. Starting to get onto dangerous ground, IMHO.

According to this ANCIENT post on TV, it fits:

So about a month ago I poured in half a bottle of the engine stop leak into the dif that @Mooseman recommended.. hasn't leaked a drop since...

I guess the Saab felt ignored, and let me know today, with a check engine light.

P0327, or bank 1, drivers side knock sensor. Yay!

I know the passenger side is a nightmare, along with the starter.. but I can't even see the one on the driver's side.

Help?

I'M BACK!!!!

LOL

New day, New problem.

On my way to work this morning, it's snowing and raining here, go to turn on my wipers, nothing. Hit the washer button, headlight washers turn on, but not the windshield washers. Flip the wipers to high, they work. But will not park. Washers also work on high, but still won't park.

I'm thinking this is a bad motor/ motor board, but not sure...

Help! (Again!)

Could be a bad switch or wiring. Check the schematics and follow the power and grounds.

The fact that the headlight washer works (at every fourth press) tells me that the BCM is receiving the signal for the washer. The windshield washer pump or relay may just be dead. And maybe coincidentally the wiper motor is also dead but double check the switch and power.

I tested it a bit further, the washer works, just have to hold it a bit longer.

Its just the intermittent wipers, and low speed wipers. High speed work fine.

It did this last week when I was coming out of a car-wash. But then about a block later, they started working normally. Thought it was just a hickup of the system. Guess I was wrong....

Im thinking its the wiper board because of the low high speed working, but low speed not working, and not parking in high speed or any other location.

There are 2 9-7x in local yards, both 4.2, a 2005, and a 2007.

What should I grab to fix this wiper problem? Or grab both the wiper motor, and wiper switch.

I am thinking the wiper motor is the same across all the GMT360s?

Per my parts search, its the same motor, and logic board, for a simalarly equipped Envoy, as the Saab.

I am fairly certain its the logic board.

But at a price of 200-300 bucks! I am thinking I am going to try a used/salvaged one!

I'd go used as well. One note though I noticed, the 2002's have their own motor along with the 2003-2004 Ascenders. All other years are the same.

Haven't heard of these failing so it's not a common occurrence.

Found another yard that had a low mileage 2006 9-7x 5.3i. Engine was completely cut out. Body was near mint, except for the front passenger fender, and hood... you know, the ones I need.

Anyways grabbed the wiper motor assembly, headlight switch, wiper switch, washer spray nozzles, and minty steering wheel controls. Just got done installing new to me wiper assembly, and works perfectly.

40 bucks in parts, certainly a lot cheaper than the 200-250 for a new one.

So it was the motor control board. I guess as these trucks age, they will fail more often.

The Saab got hit pretty good last night with Hail.. Im sure the insurance is going to total it out, but who knows. Either way, there is no point in repairing it. So I will buy it back, and keep on trucking. Glass is still in tact, so theres that. Just the body work is not purty!

Shame really, she was a nice and clean truck, with only a small ding on the fender, and a rattle in the back window. Now...... Yea..

Hail can really do a number on a vehicle.
It does...

My Aztek got totalled for hail last year
My Envoy got hit, but not totalled, for hail last year (still need to decide to repair, or pocket the check)
Now my Saab got hit
And I need to check the Saturn for hail damage too.

Well, they totalled the Saab. Valued it 5300, but for some reason I am only getting 3300.

Im into it for 4000.. And I am keeping it, with a clean title, so I am good.

I think they are going to total the Envoy too. On hold with the insurance company now.

So they reevaluated the claim from 2 years ago on the Envoy, and claimed a total loss.

So all my cars are now total losses from hail, except the Saturn. Once it's out of the body shop, putting full coverage on it. Cause I know there will be more hail!
